Protect Your Investment
Comprehensive Heating System Maintenance
Regular maintenance is the key to extending the life of your heating system and ensuring it runs efficiently and safely. AA Service Co. offers comprehensive heating tune-ups designed to prepare your furnace, boiler, or heat pump for the demanding Chicago winter. An annual inspection and cleaning can prevent unexpected breakdowns, lower your energy bills, and improve your home’s indoor air quality. Don’t wait for a problem to arise before calling for service.
During a maintenance visit, our technicians perform a multi-point inspection, cleaning key components, checking electrical connections, testing safety controls, and lubricating moving parts. This proactive service identifies and addresses minor issues before they can escalate into major, costly repairs. Scheduling a tune-up each fall is the best way to ensure reliable performance all season long.

Smart Savings
Improving Your Home's Energy Efficiency
An inefficient heating system doesn’t just struggle to keep you warm—it also puts a strain on your wallet. At AA Service Co., we focus on solutions that enhance your comfort while reducing your monthly energy consumption. A professional repair on a faulty component or a comprehensive annual tune-up can restore your system to its factory efficiency standards, translating directly into lower heating bills throughout the winter.
When it’s time for a new system, we guide homeowners in Evanston and Lake Bluff toward modern, high-efficiency furnaces and boilers that can significantly cut energy usage. Today’s heating technology is more advanced than ever, with AFUE (Annual Fuel Utilization Efficiency) ratings exceeding 95%. This means over 95% of the fuel you pay for is converted into usable heat, compared to as little as 60-70% for older models. We help you capitalize on these advancements for long-term savings.
Beyond the equipment itself, our technicians can identify other factors impacting your home’s efficiency, such as thermostat placement or airflow issues. By taking a holistic approach, we ensure your entire heating system works smarter, not harder. This commitment to efficiency helps you save money, reduce your carbon footprint, and enjoy a more consistently comfortable home.

Your Questions Answered
Frequently Asked Questions About Heating Services
To help you better understand your home’s heating needs, we’ve compiled answers to some of the most common questions we receive from homeowners in the Chicagoland area. If you have a question that isn’t answered here, please don’t hesitate to reach out to our knowledgeable team.
How often should I have my furnace serviced?
We strongly recommend having your furnace or heating system professionally serviced once a year, ideally in the fall before the heating season begins. This preventative maintenance ensures safety, improves efficiency, and helps prevent unexpected breakdowns during the winter.
What are the signs that I might need a new furnace?
Common indicators include the age of the furnace (typically 15-20 years), a significant increase in your energy bills, frequent and costly repairs, inconsistent heating from room to room, and unusual noises like rattling or banging.
Do you offer emergency heating services?
Yes, we offer 24/7 emergency heating repair services. We understand that heating failures can happen at any time, and our on-call technicians are ready to provide prompt and reliable service day or night.
What's the difference between a furnace and a boiler?
A furnace heats air that is then distributed throughout your home via a ductwork system (forced air). A boiler heats water, creating either hot water or steam that is circulated through pipes to radiators, baseboard heaters, or radiant flooring to heat the home.
How can I improve my heating system's efficiency?
Besides scheduling annual maintenance, you can improve efficiency by regularly changing your air filter (every 1-3 months), sealing air leaks around windows and doors, ensuring your attic is properly insulated, and upgrading to a programmable or smart thermostat.
Still Have Questions About Your Heating System?
Your comfort and peace of mind are our top priorities. If you have any other questions or concerns about your home’s heating, our experienced and friendly team is always ready to provide clear answers and expert advice.
